Spawner Bug Fix Mod addresses a bug which causes lag in mods that create custom spawners with endermen and when mapmakers or players use an endermen egg on a spawner. For example, Dungeon Crawl which we use in Two Guys Modpack creates endermen spawners. It fixes this bug: Some entities do not render inside of spawners and producing error log spam in console, potentially causing lag.
Detailed Bug Description:
Mob Spawners do not render a “mini” mob visual for the following entities:
- Bee
- Enderman
- Polar Bear
- Wolf
- Zombified Piglin
- Evoker Fangs
When the game attempts to render them but fails, it also produces an error message in the console over and over again, which can potentially cause a lot of lag in the world, especially when lots of spawners are used.
